Glad to see your neutral switch problem turned out to be no big deal! I think I discussed priming your oil pump in a previous post - maybe not in this thread. I realize you do not have the manual wheel on your pump that we have on the older ones here in the US, (just as well - one less seal to leak!) but gravity should be fine with a bit of patience. I can't recall ever disagreeing with any of Teaser's advice, but I like rather a lot more oil than that starting a fresh engine. No doubt the oil you use will have an impact on how much is good, but the downside on more than is needed is minor and to my way of thinking irrelevant. Too little is definitely bad. In any event, if you assembled your engine with 2 stroke oil, it should be well protected for starting. I always simply start my engines normally after setting the oil pump to be richer than "normal", and making sure the lines to the carbs are full of oil. I can't remember what I shim the oil pump to off-hand (I don't want to offer bad info - I am traveling and can't check my memory), but I will try to report back when I get home in a couple of days. Your pump could also have more differences besides the absent manual wheel, so what I do may not even matter. Regardless, assuming your pump is working properly, once gravity has filled the supply line from the tank to the pump, you should be able to hold the throttle wide open (or hold the cable to the pump wide open) and kick the engine over and fill the carb lines. You will have to kick a lot, but it will work. Alternatively, you can start on premix, which is foolproof. If I did that, I would start a fresh motor at 20 to 1 ratio. There is no downside to too much oil until plugs foul on a fresh motor. For what it's worth, I am driving today a brand new 350 motor, now with 900 miles on it (within this week!), points/condenser ignition, oiled as just described, with the same spark plugs it started on. It smokes too much, but runs fabulous - can't wait to get it back home to dial down the pump!
